SportLegs employs lactate, your body's natural muscle fuel, to support optimal function of your lactate energy system. SportLegs is 86.4% lactate and consumed an hour before exercise it increases blood lactate levels which prevents your muscles from overproducing lactate and instead focus on consuming it as a key carbohydrate for muscle fuel. Improved lactate utilization noticeably increases Lactate Threshold (LT) and minimizes excess Lactic Acid buildup up that can contribute to post work out soreness.
